Writing to Address 0F causes the ADM1023 to perform a single measurement. It is not a data register as such; thus, it does not matter what data is written to it. Table 4. Offset Values Offset Registers Remote Temperature 0x11 0x12 Offset Value With Offset Without Offset 1111 1100 0000 0000 −4 °C 14 °C 18 °C 1111 1111 0000 0000 −1 °C 17 °C 18 °C 1111 1111 1110 0000 −0.125 °C 17.875 °C 18 °C 0000 0000 0000 0000 0 °C 18 °C 18 °C 0000 0000 0010 0000 +0.125 °C 18.125 °C 18 °C 0000 0001 0000 0000 +1 °C 19 °C 18 °C 0000 0100 0000 0000 +4 °C 22 °C 18 °C Status Register Bit 7 of the status register (see Table 5) indicates that the ADC is busy converting when it is high. Bit 6 to Bit 3 are flags indicating the results of the limit comparisons. If the local and/or remote temperature measurement is above the corresponding high temperature limit or below the corresponding low temperature limit, one or more of these flags will be set. Bit 2 is a flag that is set if the remote temperature sensor is open−circuit. These five flags are NOR’d together, so that if any of them are high, the ALERT interrupt latch is set, and the ALERT output goes low. Reading the status register clears the five flag bits, provided the error conditions that caused the flags to be set have gone away. While a limit comparator is tripped due to a value register containing an out−of−limit measurement or the sensor is open−circuit, the corresponding flag bit cannot be reset. A flag bit can be reset only if the corresponding value register contains an in−limit measurement, or the sensor is good. The ALERT interrupt latch is not reset by reading the status register, but it resets when the ALERT output has been serviced by the master reading the device address, provided the error condition has gone away and the status register flag bits have been reset. |
